We have a Cisco 2106 WLC that has a static IP Address and was working fine but now we can not access any of the control box settings through the web or connect to any of the access points. If I type in the the Static IP address into an IE browser window, I normally could access and change settings on the control box but now I can't. I tried pinging the IP address and I do not get a reply. Laptops can see the wireless network but can not connect to it. It says that credentials are not correct. We have had some lightning storms in the area that took out some other equipment but was wondering how we could verify if this box is bad or if it is a different issue. Any help, solutions, or point me in the right direcion is appreciated!
